The output information of the camera is supplied to the hue, saturation, brightness, and conversion unit 32 installed in the color measurement unit 3, and used as color image information, saturation image information, and brightness image information for use in color vision measurement of the object to be measured. Convert it to output. Based on the image information output from the color measurement unit 3, the feature extraction quantification unit 4 extracts the feature amount used for the measurement of the color to be measured, and the feature extraction information 4 outputs this feature extraction quantification 4. Based on the color analysis unit 5, the color sense of the material under measurement is determined, and at the same time, the feature amount information of the feature extraction quantification unit 4 is supplied to the image processing display unit 6 for display.
